Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of Chinese Patent Application Serial Number 201810449205.6, filed on May 11, 2018, and Chinese Patent Application Serial Number 201810593400.6, filed on Jun. 11, 2018, the full disclosure of which is incorporated herein by reference.

BACKGROUND Technical Field

The present disclosure relates to methods and devices in wireless communication systems, and in particular to a method and a device in a wireless communication system of Cyclic Redundancy Check (CRC).

Related Art

Cyclic Redundancy Check (CRC) is a hash function that generates short and fixed-digit CRC codes based on data such as network packet or computer files. CRC is mainly used for detecting or checking errors possibly occurred after data transmission or data storage, and it performs error detection using the general division and the remainder theorem. In traditional Long Term Evolution (LTE) system, CRC has specific functions of error check and target receiver identification.

In 5G systems, in order to meet varied performance requirements posed by diversified application scenarios, Ultra-Reliable and Low Latency Communications (URLLC) becomes one of three major application scenarios in New Radio (NR) system. In URLLC, a typical scenario is presented by smaller quantity of data transmitted each time, and higher demand on transmission defer and transmission reliability. According to discussions of 3^rdGeneration Partner Project (3GPP) Radio Access Network (RAN) 1, URLLC transmission will support repetition as a transmission method to enhance transmission reliability.

SUMMARY

The inventors have found through researches that in order to meet the requirement of URLLC for high reliability, the precision of error check on URLLC transmission must be very high. However, the precision of error check provided by a maximum number of CRC bits that the present system can support is not always sufficient for reliability required by URLLC. Since the amount of information transmitted by URLLC each time is smaller, a redundancy further caused by an increasing number of CRC bits will remarkably reduce transmission efficiency. Therefore, how to improve error check precision of URLLC without rising excessive redundancy has been a problem needed to be solved.

In view of the above problem, the present disclosure provides a solution. It should be noted that though originally targeted at URLLC, the present disclosure is also applicable to other business types and application scenarios. The embodiments of a first node in the present disclosure and the characteristics in the embodiments may be applied to a second node if no conflict is incurred, and vice versa. The embodiments of the present disclosure and the characteristics in the embodiments may be mutually combined if no conflict is incurred.

The present disclosure provides a method in a first node for wireless communication, comprising:

transmitting a first radio signal in a first time window, the first time window is any time window out of M time windows, the first radio signal carries a first check bit block;

wherein an information bit block corresponding to the first check bit block comprises a first bit block; values of bits comprised in the first check bit block are related to a position of the first time window in the M time windows, or, a total number of bits comprised in the first check bit block is related to a position of the first time window in the M time windows; the first bit block is not related to a position of the first time window in the M time windows, the M is a positive integer greater than 1.

In one embodiment, a problem needed to be solved in the present disclosure is how to improve the precision of error check for URLLC without increasing total amount of CRC bits. The above method solves this problem by generating different check bit blocks for the first bit block in separate time windows of the M time windows.

In one embodiment, the above method is characterized in that the first node transmits radio signals generated by the first bit block in each time window of the M time windows, but generates check bit blocks for the first bit block using different CRC Cyclic Generator Polynomials in different time windows. An advantage of the above method is that check bit blocks in different time windows can be jointly used for error check for the first bit block, which is equivalent to increasing a total number of effective CRC bits, thus enhancing precision of error check for the first bit block. In the meanwhile, there is no increase in the number of CRC bits in actual transmission, hence the avoidance of excessive redundancy.

According to one aspect of the present disclosure, comprising:

In one embodiment, the above method is advantageous in that in a time window with lower number of CRC bits, a code rate of channel coding will be lower, so that transmission reliability for radio signals in these time windows will be higher. A target receiver of the first radio signal can correctly recover the first bit block out of radio signals received within these time windows, so as to recover a check bit block of the first bit block, for example, the first check bit block, subsequently.

According to one aspect of the present disclosure, wherein the M1 is less than the M, the first node only transmits a radio signal carrying the first bit block in the M1 time window(s) out of the M time windows.

EMBODIMENT 4

Embodiment 4 illustrates a schematic diagram of a New Radio (NR) node and a UE, as shown in FIG. 4. FIG. 4 is a block diagram illustrating a UE 450 and a gNB 410 that are in communication with each other in access network.

The gNB 410 comprises a controller/processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a channel encoder 477, a channel decoder 478, a transmitter/receiver 418 and an antenna 420.

The UE 450 comprises a controller/processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a channel encoder 457, a channel decoder 458, a transmitter/receiver 454 and an antenna 452.

In downlink (DL) transmission, at the gNB 410, a higher-layer packet from a core network is provided to the controller/processor 475. The controller/processor 475 provides a function of the L2 layer. In DL transmission, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation for the UE 450 based on various priorities. The controller/processor 475 is also in charge of HARQ operation, retransmission of a lost packet, and a signaling to the UE450. The transmitting processor 416 and the channel encoder 477 perform signal processing functions used for the L1 layer (that is, PHY). The channel encoder 477 performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the UE 450 side. The transmitting processor 416 implements the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.) and performs spatial precoding/beamforming on encoded and modulated symbols to generate one or more spatial streams. The transmitting processor 416 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the transmitting processor 416 into a radio frequency (RF) stream. Each radio frequency stream is later provided to different antennas 420.

In downlink (DL) transmission, at the UE 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the channel decoder 458 perform radio processing functions of the L1 layer. The receiving processor 456 converts the baseband multicarrier symbol stream from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein a reference signal is used for channel estimation, while physical layer data is subjected to multi-antenna detection in the receiving processor 456 to recover any UE 450-targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the channel decoder 458 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the gNB 410. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 performs functions of the L2 layer. The controller/processor 459 can be connected to a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In downlink transmission, the controller/processor provides demultiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing. The controller/processor 459 also performs error detection using ACK and/or NACK protocols as a way to support HARQ operation.

In uplink (UL) transmission, at the UE 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of the gNB 410 described in DL transmission, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the gNB 410 so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operation, retransmission of a lost packet, and a signaling to the gNB 410. The channel encoder 457 performs channel coding. Encoded data is modulated into multicarrier/single-carrier symbol streams through modulation and multi-antenna spatial precoding/beamforming performed by the transmitting processor 468, and then modulated symbol streams are provided from the transmitters 454 to each antenna 452. Each transmitter 454 first converts a baseband symbol stream provided by the transmitting processor 468 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.

In uplink (UL) transmission, the function of the gNB 410 is similar to the receiving function of the UE 450 described in DL transmission. Each receiver 418 receives a radio frequency signal via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the receiving processor 470. The receiving processor 470 and the channel decoder 478 jointly provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be connected with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. In UL transmission, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the UE 450. The higher-layer packet coming from the controller/processor 475 may be provided to the core network. The controller/processor 475 can also perform error detection using ACK and/or NACK protocols to support HARQ operation.
